DPX Question

Can anyone answer a couple questions concerning some capabilities for composite packages.

We are doing quite a bit in the DPX header. Timecode, audio, etc...and need to confirm that if you take two DPX frames and composite them together, can you maintain the DPX header information from one, both or do you have a choice to determine which one?

We are also trying to confirm other tools that can do this.

If your familiar with Graphics Magic, you can open up the header information to confirm this.

If anyone requires frames with header information, let me know. We are not concerned with what the image looks like for this test and only if the header information can be maintained.

RaveHD can capture and playout the frames without having to convert the audio out of the header, so we are just trying to see what else can get along in the playground.
